Here is a guide to how speech usually develops in tamariki (children) Speech development may vary across languages.

What are early, middle and later speech sounds?

Early, middle and later speech sounds help us think about the order that tamariki learn to say speech sounds.

Here is the approximate order that speech sounds develop in tamariki. They develop from the time a child starts using words until the early years at school. Although the age range extends to 8 years, most children will be using these sounds earlier than that1.

Early (18 mths to 3 yrs)

m n y b w d p h

Middle (2 to 6 yrs)

t ng (talking) k g f v ch j

Later (3 to 8 yrs)

sh zh (measure) l r s zth (think) th (that)

How will my child's speech develop?

Children's speech generally gets easier to understand as they get older. Here's a guide2:

  • by 2 years of age tamariki can be understood by familiar adults most of the time
  • by 3 years of age tamariki can be understood by unfamiliar adults most of the time
  • by 4 years of age tamariki can be understood by unfamiliar adults almost all of the time
  • by 5 years of age tamariki can be understood by unfamiliar adults all of the time

What are some tips to help my child's speech development?

Be interested

Show your child that you are interested in what they say, not how they say it.

Repeat tricky sounds

Help your child to learn how to say tricky sounds by repeating them correctly as naturally as possible. For example, if your child says "bish", you say "yes it's a big fish, isn't it?"

Talk face to face

Get face to face with your child so that they can watch the way you say words.
